Cordless vacuum cuts out intermittently when moved or tilted, then restarts when repositioned.

Safety first: Remove the battery before opening the housing.

• Check battery fit: Ensure the battery clicks firmly into place. If it feels loose or can be wiggled easily, the latch or contacts may be worn.
• Inspect contacts: Look at the metal contacts on the battery and vacuum body. Clean with a dry cloth. If they are flattened or bent, they may not maintain contact; replace the battery or contact block as needed.
• Wiggle test: With the vacuum running (battery installed), gently tap or wiggle the battery and handle. If the unit cuts out, the issue is likely at the battery connection or internal wiring.
• Open housing (advanced): Remove screws and open the main body to inspect wiring connectors. Reseat any loose connectors and look for cracked solder joints on the PCB, especially at high-current points.
• Replace worn parts: Replace the battery, contact block, or main PCB if physical damage or wear is found.
